Wow, thank you guys for the input:D. Maybe I'll quit the malaise traps because for now I'm the only person that will take the responsability to deal with the insects. And there isn't just one site, but five.
I'm thinking of using some families of Coleoptera, Diptera, Odonata, Hymenoptera and Lepidoptera....I hope that it isn't too much for just one person.:|
As new questions arise, I'll be asking for your help.;)
